The Panthera is a prototype 4-seat airplane being developed by Pipistrel in Slovenia. A gasoline-powered version of the Panthera is being developed first and has completed spin testing for certification.
Pipistrel is planning battery electric and hybrid electric versions of the Panthera. As of February 2016, a prototype hybrid electric propulsion system has been mounted on a Panthera airframe and ground-tested.
